Boya BY-M1 Lavalier

The budget lavalier that's launched a thousand YouTube channels. Six-meter cord, omnidirectional, works with phones, DSLRs, and computers via a switch on the body. The audio is genuinely usable — not pro-grade, but better than your laptop mic by a wide margin. Picks up everything around you because it's omni, so quiet rooms only.

The Boya BY-M1 has been the budget lavalier mic recommendation for nearly a decade and 2026 hasn't changed the math. Omnidirectional condenser capsule on a clip, six-meter (about 20-foot) cord, a 3.5mm TRRS plug, and a small battery compartment on the body with a switch that toggles between camera mode (no power needed) and smartphone/PC mode (LR44 battery powers the mic). Includes a foam windscreen. The audio quality is what you'd expect for $20 — clear, present, more than adequate for video voiceovers, interviews on the go, walking-and-talking content, and emergency podcast recording when your main mic dies. It's noticeably better than a phone's built-in mic and noticeably worse than a $150 lav like the Rode SmartLav+ or a wireless system like the Rode Wireless GO II. The omnidirectional pattern is the biggest practical limit: it picks up everything in the room with equal sensitivity, which means recording in a noisy cafe, near an air conditioner, or in a reverberant space will sound exactly like that. Use it in quiet, treated spaces. The TRRS connector is the second weak point — adapter required for newer iPhones, and the connector itself can develop crackle after months of plug-cycling. For the price, it's hard to find a better starter mic — the included windscreen and detachable lapel clip round out the package.
